If you add items to a crate using the commands: addMagazineCargoGlobal or addWeaponCargoGlobal the bar at the bottom of the crate inventory will not update to reflect how full it is, however, after adding a lot of items (Add what i assume is fill the crate over it's limit), the bar will still appear empty, but when trying to drag an item into the crate it will appear red, although it will show the bar with how much volume that item would add.
